我使用Java的Swing工具箱设置了一个大型GUI(比以前做的任何工作都大),并且我想设置自己的自定义配色方案来绘制颜色,以便所有颜色定义在一个地方。为此,我决定制作一个名为ColorPalette
(应用于https://stackoverflow.com/a/7486111/4547020后)的伪静态顶级类别,其中包含SchemeEnum
,其中程序员为整个GUI设置颜色方案。Java Swing模块化配色方案
我希望颜色选择独立于颜色方案的知识。有没有人知道设计模式或有效的方法来做到这一点?我不完全相信,我目前的设置是实现这一目标的最佳方式,但我想建立一个模块化的设计,它不会打扰添加更多ColorEnums
或SchemeEnums
(在编译时,不运行)。
为了清楚起见,我想程序员能够简单地选择一个ColorEnum
并获得返回的基础上,ColorEnum
和定义SchemeEnum
一个java.awt.Color
对象。
例如:
// Use the BASIC color scheme
ColorPalette.setCurrentScheme(ColorPalette.SchemeEnum.BASIC);
// Set button backgrounds
testButton.setBackground(ColorPalette.ColorEnum.DARK_RED.getColor());
testButton2.setBackground(ColorPalette.ColorEnum.BLUE.getColor());
应该比
// Use the DARK color scheme
ColorPalette.setCurrentScheme(ColorPalette.SchemeEnum.DARK);
// Set button backgrounds
testButton.setBackground(ColorPalette.ColorEnum.DARK_RED.getColor());
testButton2.setBackground(ColorPalette.ColorEnum.BLUE.getColor());
返回不同Color
对象,因为它们有不同的SchemeEnums
,即使它们是从ColorPalette
请求相同的颜色。这样,更改一行代码更改(或颜色甚至可以在运行时更改)GUI中更改GUI中的每种颜色。
我听说过HashTables被用于这种大型数据存储,但我不知道它们是如何工作的。可能在这里适用?
这是我的代码到目前为止。提前致谢!

觉得这将是简单直接定义颜色到UIManager的或创建自己的外观和感觉,也许使用[Synth](http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/synth.html) – MadProgrammer 2015-02-09 20:43:32
大多数JComponents都有属性数组,例如作为JButton,这些属性对于所有可能的事件(选择,按下,武装,...)都是不同的,使用自定义L&F,在某些情况下可以设置颜色方案(以避免重新发明轮子) – mKorbel 2015-02-10 08:30:35
